silicone vacuum lines?
so im doing a swap and i want to change all the vacuum lines from the stock rubber to silicone. I would like to order them from hosetechniques.com, however they do not have a vehicle specific kit for the sc300 only the IS300. I cant seem to find ANYWHERE what size hoses are on the engine. since hose techniques nor I know the sizes, i dont know what to order. there should only be 3 or 4 sizes on the engine. most of the vacuum lines are the same size just different lenghts. Can anyone help?

This is what is in the 87 supra kit, so you can go off of it (or just buy that kit from them). The thing about 2jzge is that there is far less in the way of vacuum lines, so this type of kit would probably leave you much extra.
3.5mm hose 15 feet (emissions)
4.0mm hose 7 feet (vacuum)
6.0mm hose 6.5 feet (bigger vacuum ports like power steering, boost signal)
8.0mm hose 3.5 feet (brake booster and other bigger ports)
if you wanted to do the pcv vent hoses, that would be 10mm
